Check Digit Verification of cas no

The CAS Registry Mumber 1049682-29-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,6,8 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1049682-29:
(9*1)+(8*0)+(7*4)+(6*9)+(5*6)+(4*8)+(3*2)+(2*2)+(1*9)=172
172 % 10 = 2
So 1049682-29-2 is a valid CAS Registry Number.

, p. 1103 - 1108 (2008/12/20)

(Chemical Equation Presented) A series of furo[3,4-e]pyrazolo[3,4-b] pyridine analogues of podophylloxin were synthesized via three-component reactions of aldehydes, 3-methyl-1-phenyl-1H-pyrazol-5-amine and tetronic acid in water under microwave irradiation without catalyst. This efficient synthesis not only offers an economical and green synthetic strategy to this class of significant compounds but also enriches the investigations on microwave-assisted synthesis in water.
